Don't be a killjoy, man. A naked Japanese woman sushi table event essentially fulfills everything I need for stuff in the "things I will partake in when I am rich and have lost my soul" category.

1. Pointlessly extravagant
2. Needlessly and gratuitously demeaning
3. Emblematic of a cultural class exploitation
4. You get to make jokes about where the raw fish smell is really coming from lol
5. Caters to lechery
6. Food probably also tasty

Knowing the Japanese, it's something with about a thousand little etiquette rules that no one knows about until they break one, like "you can slip a finger in her if and only if the last piece you ate off her body was maguro."
